Since you're creator of PmWiki and (I think) originator of the right-arrow link syntax, I'm particualrly interested in your ideas on Alternate Link Syntax Proposal. Why did you introduce this syntax? Did it create any problems or confusion for your users? Do you still feel it's a good idea?

Yes, I originated the right-arrow syntax. It works extremely well, and my authors don't seem to have any trouble with it. There are some authors who exclusively use the arrow syntax, some who exclusively use the pipe syntax, and some (like myself) who use both depending on what reads better in the markup.

I've never heard from anyone who found the additional arrow syntax to be confusing or difficult to work with. I still think it's a good idea.
